I use the public specs from sdcard.org for more or less everything. I also have a MMC 4 spec, which was generously donated to me by Nokia. Unfortunately I am not allowed to pass that on. I can look things up for people if they have specific questions though.
The MMC Association has merged with JEDEC, so now everyone can download the specs, e.g. http://www.jedec.org/download/search/JESD84-A44.pdf .
